INTRODUCTION
The TAMSON model TV12 bath is designed to perform
as ultra stable visability bath. The intende use is
kinematic viscosity measurement and sensor calibration.
6.1 General
The heat input is controlled by a microprocessor system.
A special optimized electronic temperature measurement
circuit ensures reproducibility of operation conditions.
The bath has an integrated cooling coil as standard, for
rapidly reducing bath temperature alternatively for
working at or slightly below ambient temperature.
6.2 Construction
The TAMSON baths are constructed entirely from
corrosion-resistant materials
– stainless steel and brass
– entirely. The central microprocessor within the control
module manages and controls the functions for
temperature measuring regulation, program storage,
safety control and error coding.
6.3 Stirrer
A circulation stirrer is built-in for uniform temperature
distribution within the bath.
6.4 Temperature control and setting
The bath temperature is regulated using a Pt-100
temperature
probe
Class
A
connected
to
a
microprocessor module. The advanced electronic control
system continually computes the energy input required
for optimal temperature accuracy and stability. The
controller will activate the heaters partially or in full,
depending on the difference between actual bath
temperature and set point, which also depends on the
type of bath fluid used and working conditions. This
process does not interfere electrically with other
equipment since all heating elements are switched in
zero-cross mode. Through the application of an
especially developed inlet circuit for the temperature
probe, the sensitivity to external interference has been
reduced to a minimum. The required temperature is set
by means of encoder switch on the front panel. An
absolute temperature offset is provided with a resolution
of 0.01°C. This fine-tuning can be carried out at any time
during operation of the bath.
